March.~\ GREEN-HOUSE REPOTTING. 205 



Aloysa citriodora, known in our collections as verbena 

 triphylla. The flowers are small, in long spikes of a pale 

 lilac colour: the celebrity of the plant is in the delightful 

 odour of its foliage, which is linear, lanceolate, and ternate. 

 It is of very easy culture, and has been known to survive 

 winter in the open air in Philadelphia. Where large 

 plants are desired, they should be planted in the ground 

 during summer, and lifted in November, and put in a dry 

 cellar or under the stage in the green-house. Before they 

 begin to grow in the spring, trim the plants into a neat 

 shape. (Soil No. 9.) 



Alstrcemerias, about sixteen species, all exceedingly de- 

 sirable, and many of them particularly beautiful; such are 

 A. durea, golden flowered ; A. acutifdlia, scarlet ; A. 

 Hookerii, rose-coloured ; A. pelegrina, elegantly spotted ; 

 A. pulchella, red flowered, and will grow six feet high, 

 having its shoots crowned with a profusion of flowers ; A. 

 psittadna, red, yellow and green ; A. tricolor, black, 

 white and yellow ; very beautiful. They have, generally, 

 tuberous roots, and should be potted into" fresh soil as soon 

 as they show symptoms of growth, and they will require 

 repotting about every rrtonth previous to flowering, taking 

 care never to break the ball of earth while they are in a 

 growing state. (Soil No. 10.) 



Amaryllis. This is a genus of splendid flowering bulbs, 

 containing about eighty species and one hundred and forty 

 varieties. They are natives of South America, but more 

 than one-half of them are hybrids grown from seed by cul- 

 tivators. They are generally kept in the hot-house, but in 

 our climate will do perfectly well in the green-house ; and 

 we have no doubt that in a few years many of them will be 

 so acclimated, as to keep as garden bulbs, planting about 

 the end of April, and lifting them in October. As the 

 beauty of these plants is in the flowers, it will be proper 

 to give a small description of a few of them. A. Johnsoni, 

 the flowers are a deep scarlet, with a white streak in the 

 centre of each petal, four bloom on a stem of about two 

 feet, each flower about six inches in diameter : a bulb well 

 established has two stems. A. regina, Mexican Lily, has 

 large sparlet pendent flowers, tube of the flower frmged- 

 like, with three or four on the stem. A. viftata is an 

 admired species with scarlet flowers, striped with pure
